PROBLEM TO BE SOLVED: To provide an electric blower capable of improving reliability of a battery.SOLUTION: An electric blower includes a blower motor 21 that is driven by an inverter 22 for converting DC power from a battery 10 to AC power. The inverter 22 changes rotation speed of the blower motor 21 depending on the residual amount of the battery 10; changes time until the rotation speed of the blower motor 21 has become steady rotary speed, depending on the residual amount of the battery 10; or changes regenerative electric energy flowing from the blower motor 21 to the battery 10, depending on the residual amount of the battery 10.SELECTED DRAWING: Figure 3 |
